Primary Irritation

Scabies is an infectious skin disease caused by mite Sarcoptes scabiei. Neem tree (Azadirachta indica) has the potential to be used as an anti-parasite due to the presence of azadirachtin compound that is commonly found in the seeds. The aim of this study was to evaluate in-vivo effectiveness of neem oil as an anti-scabies. This study used an experimental method.  The effectiveness of the cream as an anti-scabies was tested on New Zealand white rabbits which were infected with scabies. Permethrin cream was used as a positive control and cream base was used as a negative control.  Cream was applied once daily and left for 8 hours. The data were analyzed using Kruskal Wallis and Mann Whitney. Dermal acute irritation test was performed by applying  0.5 g cream on the rabbit dorsal. We found that 5% neem oil cream was effective as an anti-scabies with 20-21 days recovery time. The recovery time is longer than permethrin cream (7-8 days), but shorter compared to negative control with recovery time over 30 days. Primary irritation index for 5% neem oil creams was 0, indicating negligible irritation category. In conclusion, A. indica cream was effective for the treatment of scabies although its recovery time is shorter than permethrin cream.  Keywords: effectiveness test, irritation test, neem oil cream, scabies

This study aimed to develop oral microemulsions (MEs) containing M. alba extract. The stability study of the extract incorporated in the ME was also included. First, pseudo-ternary phase diagrams were constructed using caprylic/capric triglyceride (oil), PEG-8 caprylic/capric glycerides (S), polyglyceryl-3 diisostearate (CoS). Propylene glycol (PG) was used as a cosolvent. Then, the formulations were chosen to incorporate MSE and subjected to stability testing at 4o C, room temperature (RT) and 45o C at 75% RH for 8 weeks. Physical stability of the formulations was assessed by visual observation on the precipitation, phase separation and cloud point. Chemical stability was determined by quantitative analysis of oxyresveratrol using high performance liquid chromatography (HPLC). The results showed that with increasing the ratio of S/CoS, the area of ME existing region in phase diagrams increased. The addition of PG into aqueous phase at ratio 1:1 slightly affected the formation of MEs. Physical stability was not affected by temperature but was influenced by the components of the formulations. However, degradation of the extract was affected by both temperature and components of the formulations. The extract was stable at 4o C and RT. However, at 45o C, it degraded about 16-57%, depending on the components of the formulations. The best ME formulation consisted of 10% caprylic/capric triglyceride, 80% PEG-8 caprylic/capric glycerides and polyglyceryl-3 diisostearate (4:1), and 10% water and PG (1:1).

AbstractThe authentication of neem oil and its blending with inexpensive vegetable oil, such as, palm oil is a common practice in the neem oil industry. This study was conducted to investigate the neem kernel (Azadirachta indica) oil (NKO) by blending with palm oil and characterize it by studying its effect on the physicochemical properties, dielectric properties and fatty acid profiles of the blend. Blending significantly influenced the color, dielectric, structural and antimicrobial properties of the virgin oil. The NKO was rich in oleic (44.97%), stearic (21.27%), palmitic (16.88%) and linoleic acids (14.08%). The addition of palm oil into NKO significantly influenced the fatty acids profile , which was further confirmed by the FTIR spectra and the dielectric data. Overall, determination of moisture content, palmitic and stearic acid content, color parameter "a" and dielectric measurements were found to be fastest and precise way to detect the NKO and PO blends.

Objective: This study aimed to develop the nanostructured lipid carriers (NLCs) for repairing the hair split-end and to compare the influence of NLCs charges on hair binding effects. Methods: NLCs was prepared by a high-pressure homogenization technique. The difference solid lipids were selected to obtain the negatively charged NLCs (N-NLCs) and positively charged NLCs (P-NLCs). The physical characterizations of both NLCs were examined. The NLCs cream was prepared by mixing NLCs into a cream base. Then, the hair split-end binding effects of the NLCs cream were assessed. The physical stability of both NLCs were investigated by kept at room temperature for 6 mo. Results: The N-NLCs and P-NLCs were successfully prepared with a zeta potential of -44.4 mV and 32.3 mV, respectively. They were a spherical shape with a similar mean size of ~150-160 nm. The hair split-end evaluation showed that both NLCs illustrated similar hair split-end binding time of more than 3 d, suggesting no extra benefit from the positively charged of P-NLCs. On the contrary, the cream base and commercial product showed a short binding time of <8 h. Furthermore, after 6-mo storage, N-NLCs demonstrated good physical stability without particle aggregation, while P-NLCs exhibited a phase separation. Conclusion: The developed NLCs is a novel alternative for the leave-on product, which would be highly benefits for hair split-end repairing.
